Throughout figures 1 to 11 of the drawings,
similar reference numerals have been allocated to
similar parts. ~he same applies to Figs~ 12 to 17.
Referring firstly to Figs. 1 bo 9, a first
preferred embodiment of the hinge structure of the
invention eomprises a ~irst hinge body indicated
generally by the ~eference numeral 20 and a second
hinge body indicated generaLly by the re~erence

Connecting means are provided to connect the
two bodies 20, 21 in such a way as to enable them
to swing or hinge r~ative to one another from the
co~dition shown in Figs. 1 and 4. These connecting
means comprise first and second webs or ~traps 26,
27 each of which corresponds to approximately one
half o~ the extent o~ the hinge b.ody ~aces which
confront in the full open condition of bhe hinge and
which together form an inter.nediate spacer between
lO the bodies 20, 21. ~hese webs or straps 269 27
are ~ormed integrally wibh the bodie6, being of a
suitable flexible plastics material ~uch as poly-
propylene, and as can be seen:the web or strap 26
provides a connection be-tween the ~irst hinge edge
15 22 of the first hinge body 20 and the sscond hinge
edge 25 of the sscond hinge body 21. Conversely,
the second web or strap 27 pro~ides a connection
between the second hlnge edge 23 of the first hinge
body 20 and the first hinge edge 24 of the second
20 hin~9 body 21.
~ Thi:~srrangemsnt of~the webs or strap~ 26, 27
enables~to hinge bodies, 20,21 to be swung, as desired,
rslative to ons anothsr,;¦to cns~ side o~ the other

toward~ either of it9 closed-together condition~ (o~
which one only is illustrated, ~ee Figo 8)~ In
~winging to the one side, as shown in Figs. 7 ana 8,
the hin~e bodies 20, 21 pivot relative to one another
about a pivot axis corresponding approximately to
the registering hinge edges 23 and 25. During this
swinging movement 9 the web 26 lies against the body
20 and the web 27 lies against the body 21. As can
be seen from Fig. 9 (which corresponds to ~ig. 7
but shows the bodies having been ~wung to the opposite
side) during th~ swinging movement in the QppOsite
direction, the web 26 lies again6t the body 21 and
the web 27 lie~ against the body 2~.
The ~oregoing describes the basic ~orm of the -~
pre~erred embodiment o~ the hinge o~ the invention,
and it will be ~ppreoiated that the two hinge bodies
: 20, 21 can be adapted in any convenient manner bo
enable components to be ~i~ed thereto which are requir-
ed to pivot relative to one another, such as a ~oor
or window and its frame, a oonbaineir and its lid,
and ~o on.

particularly simple manner which enables it to be
produced and assembled conveniently and econo~ically,
it is formed from two components, as will be evident
from consideration particularly o~ ~igs. 1 to 4
5 o~ the drawings. ~he hinge body 20 comprises two
body sections 40, 42 and the hinge body 21 correspond-
ingly comprise two body sections 41, 43. Each such
section pro~ide~ a respective one o~ the hinge edges
22, 23, 24 and 25 so that each section 40, 42 of the
10 body 20 is connected to the complementary section 41,
43 o~ the othe* body 21~by the respective web 26, 27
to form a respective mouldable unit. As previousIy
mentioned, these u~its (whioh are illustrated separ-
ately in Figs.`2 and 3) are prefe~ably of polypropy-
15 lene which provides ~ood bending properties at thejunctions between the webs and the body sections.
,
In ~igs. 2 and 3, the body sectio~s o~ each unit have
been illustr~ted somewhab separatéd from one another.
In this condition they may be assèmbled together eas-
20 ily to the form shown in ~'igs. 1 ~nd 4.

indicated generally by the reference numerals 60, 61,
62 and 63, ~he respective hinge body 3ection~ each
comprising re3pective sections of these spigotsO
In the case of the body 20, the two spigots 6~, 61
are at right angle~ to one another, as also are the
spigots 62, 63 of the body 210 This arrangement
enables each hinge bodg to serve, in additlon to
being a hinge oomponent, a~ a respective corner
piece o~ a frame (indicated generally by the numeral
70 in ~ig 5) of a respective rectangular panel 71
de~ired to be hingedly connected to an adjacent
similar panel 72 ÇFig. 6?.
The ~rame 70 compriseq square section tubular
frame members 73, 74 and these are joined at the
ends of the ~ide of the panel 71 desired to be
conneoted to the panel 72 by respective ones of the
~pigots being driven therein so as to be a tight
friotion or interference fit -Thus, in ~ig, 5 and

corner pieces of the fra~e of the nex-t adjacent
panel 72. As can be seen from I'i~s. 5 and 71 in
each panel, the frame 70 is covered with an appro-
pria-te loop-pile or hook-pile ~abric layer 80
which is drawn over the frame under tension and is
welded along three edges as at 81 to form a taut
envelope.over the frame. To enable this welding
to be effected the fabric i~ preferably a vinyl or
vinyl-backed fabric. If desired, as shown in Fig.
7, this envelope may be gapped in register with
the hinge bodies 20, 21 i~ desired.
In the case of the panel 71, only two o~ the
frame corners are provided by the hinge bodies of
respective hin~e assembl1est and the other corners
of the ~rame 70 are formed by res~ective simple
block-like bodies 75 which fit by respective 9pigQt9
(not visible) similar to the spigots 60t 61 into
the respective ends of their respective ~ra~e members
to form these members into the frame. The panel 72
couId be the same 1n for~ as the panel 71, in which
case the resultant assembly would be a two-panel
assembly o~ which the panels can be arranged at an
angle to one another as shown in ~ig. l so as to be
~ree standing or can be folded against one another,
e.g. for storage.

The panel a~embly can be u~ed for dispiay,
exhibition or like purpose~, or may simply be
used as a screen in the same manner as prior known
free-standing foldable screens. In the illustrated
case, however, the panel 72 has hinge a~semblies
in accordance with the invent~on at all of its
~our corners, to enable it to be hingedly conne¢ted
to a further panel 76 who~e con~-truction is sub~tanb-
ially equal to that o~ the panel 71 and there~ore
needs ~o further description.
Referring now bo ~igs. 10 and 11, each of the
hinge bodies 20j 21 (as well as the block-like oorner
bodies 75, which may also comprise sections assembled
together) may ~e ~ormed with a respeotive opening
90 (~ig. ll)i de~ined by appropriate recesses 91 in
the registering body sections. ~he~e openings, in
use, serve each to receive a tight-fitting peg (not
shown) onto which can be engaged bhe respecbive hinge
assemblies o~ a subsbanbially identioal screen. This
arran~ement, there~ore, enables height variation o~
the screen assembly constructed using the hinges,
simply~by adding an upper row o~ panels along the
:

upper edge~ oP a lower row of panels.
Referring now to Fig~. 12 to 16, a third embodi-
ment of the hinge structure o~ the pre~ent invent~on
oomprise~ a first hinge body indicated generally by
the reference numeral 120 and a econd hinge body
indicated generally by -the reference nu~eral 121.
The fir~t hinge body 120 has parallel ~ir~t and
seco.nd hinge edge~ 122 and 1239 and the second hinge
body 121 has corresponding ~irst and second hinge
10 edges 124`and 125. Each such hinge body 120, 121
is ba~ically in the form of an approximately cubic
block, with its hinge edgeq along adjacent edges of
the block, and in the full open dispo~ition shown
.in Figs. 13 and 14 where.the two said bodies 120 and
15 121 lle substantially in alignment, the corresponding
~ides of the bodies face one another, with the hinge
edgeq 122 and 124 aligned, and the hinge edge~ 123

from the aligned condition shown in Figs. 13 and 14.
These connec-ting means comprise fir~t and second
webs or straps 126 a~d 127 ~ach of which corresponds
in width to approximately one hal~ of the height o~
5 tAe xespective hinge body faces (o~ which one only
is visible at 200 in Fig.12) which con~ront one
another ln the full open condition of the hinge shown
in ~1ig~. 13 and 14 and which together ~orm a thin
intermediate spacer between the two bodies 120 and
10 121.
~ he webs or straps 126 and 127 are connected
with the bodies 120 and 121 by each ~aid web being
formed, on each of it~ ends, with a respective en-
largement in the *orm of an integral tra~v~e rod
15 or bead 201 wh;ich fits into a respective bo~e 2~2
provided in the respective bodies 120, 121 with the
adjacent sections o~ the web~ or ~traps 126, 127
accommodated in and extending t~rough respective
slots 203 provided in the block between the bores
20 202 and the correspo~ding hinge edge~ 122, 123, 124
and 125 o~ the bodies. The web~ or straps 126 and
127 are ~ormed of a suibable flexible

plastics material such as polypropylene and, as can
be seen, the web 126 provides a connection between
the ~irst hinge edge 122 of the first hinge body 120
and the second hinge edge 125 of the second hinge
~ body 121. Conversely, the second web 127 provide~
a connection between the second hinge edge 123 o~ the
first hinge body 120 and the first hinge edge 124 o~
the second hinge body 121.
As shown in ~igs. 15 and 16, this arrangement
10 o~ the webs 126 and 127 enables the hinge bodies
120, 121 to be swung, as desired, relative to one
another, to one side or the other towards either
of its closed-together condition (o~ which one is
ill~strated in full lines and the other is shown in
15 chain-dotted line~ in Fig. 16). In swinging to the
one slde, as shown in ~ull lines in ~igs. 15 and 16,
the hinge bodies 120 and 121 pivot relative to one
another about a pivot axis corresponding appro~imately
to the registering hlnge edges 122 and 124. During
20 thi~ swinging movement, the web 127 lie~ against the
body 120 and the web 1?6 lies against the body 121.

- the dotted line positions in Figs. 15 and 16, the
web 127 lies against the body 121 and the web 126
lies against the body 120.
It will be appreciated that, as with the preceding
embodiments, the two hinge bodies 120 and 121 can be
adapted in any convenient manner to enable components
to be fi~ed thereto which are required to pivot re-
lative to one another, such as a door or window and
its frame, a container and its lid, and so on.
In this illustrated form of the hinge, each body
120 and 121 is adapted for a re~pective component
to be fixed thereto by the body being ~ormed with
integrally-moulded spigots indicated generally by the
reference numerals 160, 161, 162 and 163, the ~pigots
161 and 163 b0ing separated from their respective
bodies 120 and 121 by~ respective integrally formed
coll~rs or stops 205. In the case o~ the body 120,
the two spigots 160 and 161 are at right angles to
one another, as also are the spigots 162 and 163 o~
the body 121. This arrangemen-t enables each hinge

therefore, enables height variation of the screen
10 assembly constructed using the hinges, simply by
adding an upper row of panels along the upper edges
of a lower row of panels. Where s`uch pegs are not
provided, a respective masking plate 300 (~ig.~
having a deformable protrusion 301 for fitting tightly
15 (e.g- as a snap fit,) into the respective opening 190,
may be provided for blanking off the ends of the
hinge bodies and for ensuring thatlthe rods or beads
201 are retained in the respective' bore~ 202.

bore~ 202 being of corresponding axial depth so
that the possibility of movement o~ the rods or beads
201 in the bores 202 is minimised compared with the
Figso 12 to 16 embodiment. In this embodiment, also,
the shape of the bod~es (of which the body 121 is
representative) is somewhat different ~rom that o~
~igs. 12 to 16, and shoulders 401, 402 are provided
for abutment thereagainst of the respective ~rame
members (not shown). Moreover, the opening 190
10 extends both through the body 121 and its spi,~ot 163
to permit use of coupling pegs o~ sub~tantial axial
length.
Other modifications are possible within the scope
o~ the,~ollowlng cla ms.
